Hiroyuki Sugiyama

Hiroyuki Sugiyama is a Professor of Mechanical Engineering at the University of Iowa's College of Engineering and a Researcher at the Iowa Technology Institute. He holds a PhD from the University of Illinois at Chicago (2005) and has been with the College since 2013. His research focuses on computational multibody dynamics, railroad vehicle dynamics, tire/road interaction, and finite element methods. Key areas include flexible multibody systems, wheel/rail contact modeling, and off-road mobility simulations.

Education: PhD in Mechanical Engineering from University of Illinois at Chicago (2005); MS and BS in Mechanical Engineering from Aoyama Gakuin University, Tokyo (1999 and 1997).

Research interests span advanced modeling techniques for vehicle dynamics, including tire-soil interaction, data-driven approaches, and multiscale simulation frameworks. Recent work emphasizes hierarchical modeling, reduced-order methods, and integration of machine learning for efficiency. His studies often involve experimental validation, such as scaled roller test rigs and terrain simulations.

Publications highlight contributions to multibody systems, railway dynamics, and computational methods. His work appears in top journals and conferences, with a focus on practical applications like amphibious vehicle design and wind turbine drivetrain optimization.

Labs/Teams: Leads the Computational Multibody Dynamics Lab, developing open-source tools like the Chrono dynamics engine. Active in professional societies including the American Society of Mechanical Engineers and Society of Automotive Engineers.
